To all whom it may concern: 1

Be it known that I, Hnnnn'r Mnnnnirm; Jones, a subject of the Kin of England, i and a resident 0f-New Yor ,county andj State of New York, have invented a-certaini new and useful Improvement in Pneumatic, Cleaners, of which the following is a full, clear, and exact specification.

This invention relates more particularlyi to a class of pneumatic devices adapted.t0l

of fabricated materials.

My invention has for its object primarily to provide a form of device which is constructed so as to permit it to be manually; operated for employing currents of air by; which carpets, rugs, draperies, and like household furnishings may be effectually cleaned, thereby saving the irksome work incident to the use of a broom, brush, or other methods ordinarily used for cleaning especially in homes. This is accomplished mainly y providing a form of cleaner wherein is employed a rotatable fan for producing currents of air by which dust, or the like is suctionally extracted from the articles being cleaned. I

Another object of the. invention is to pro vide means adapted to permit the fan to be manually revolvedat a desired speed; and

still another object of the invention is to provide a receiver by which dust'may be collected, and which permits the refuse to be readily removed from the device when desired- A further object of the invention is to provide a pneumatic cleaner of simple and efficient construction.and which may be made light in weight as well as susceptible of being readily operated.

A. practical embodiment of the invention is represented in the. accompanying drawing forming a part of this specification in which similar characters of reference indicute corrcspomling parts in all the-views, ihc'suid invention lacingmore full} described hereinafter and then pointed out in the upbci'nlcd claims. a

In the .drawin s. Figure I is a sideeleration oi one form oiipncumatic cleaner embmlying my invention. Fig. 2 is a longitudinul section, partly fragmentary and partly in detail, of the cleaner. Fig.3 is a section taken on the line Il-ll of Fig. 2.

i Fig. 4 is a section taken-0n the line III-III of Fig. ,2. Fig. 5 is a view of the ring for supporting one end of the Woven bag 'used in the device. Fig. 6 is afragmentary side view of the woven bag. Fig. 7 is a side view of the supporting bracket used inthe cleaner.

The device, or :pneumatie cleaner has a barrel or tubular casing 10 which is prefer- :ably circular in shape, and said barrel may be used for cleaning articles made especially b e of any suitable circumferenceand length. Around the exterior of the barrel 10, and in proximity to one end thereof, is spun a rib 11 whereby an inner annular groove 12 is provided. The end portion of the barrel '10 which is contiguous to the rib 11 may be slightly tapered and tightly fitting this tapered end is a cap 13 which carries a'tube 14. The tube 14 is preferably of suiiicient length to extend some distance interiorly of the barrel 10 as well as extending a suitable distance beyond the exterior of the cap, and upon the free end of this extension is attached one end of a pipe .15 having a nozzle,

as '16, of the usual, or any preferred form, mounted upon its opposite end.

Theend of the barrel 10, which is opposite to. the cap 13, is soldered,.or otherwise connected' to a concentric 'rib, or flange 17 formed upon the edge of the large'opening, as 1'8, through the underside of a head 19 which is hollow so as to provide a chamber 20, and projecting from thecenter of the exterior of said head which is opposite to the large opening 18 is whose 21. Through the boss 21 is a threaded opening which is in register with an opening also formed .through the head, and in said head are outlet ports, as 21. In the opening of the boss '21 is threaded a screw22 having a concaved,

or tapered recessed end, and upon the outer end of said boss is a handle 23 for permit ting the device to be carried in the hand of a persoru Lengthwise through the barrel '10 and ad j'acent to the head 19 is an elongated opening 22, and upon the exterior of the barrel at the edge-of this opening is a housing 93'. In the side walls of the housing is pivoted a transverse short shaft 524. and at one end of the shaft is held one end of a bracket 25. This arm of the bracket 25 extends through an elongated opening in the barrel to approximately the center thereof where it is connected to oneend of a cross-plate 26, and the other end of the bracket is'fastened to the concentric rib 17 of the head 19. In a threaded opening through the cross-plate 26 is an adjustable screw 27 having in its end, which is opposed to the'screw 22, a con caved or taperedirecess. Rotatably seated in the tapered recelss of the screw 27 is one of the pointed or tattered ends of a shaft 28. The opposite endiof the shaft 28 is also "pointed, or tapered and is rotatably seated in the tapered recess of the screw 22.

Upon the shaft 28, and within the chamber 20 of the head 19, is a fan 29 having a plurality of radially disposed blades 29 which are of a formation and arrangement so that when revolved suctional currentsof air will be forced through the nozzle 1-6, through the pipe 15, through the tube 14, andinto the barrel l0. From the barrel 10 the air will be, forced into the chamber 20 of the head l9=v and exhausted through the outlet ports 21.\in said head.

On a portion bf the shaft 28 which is adjacent to the s "-ew 27 is a worm 30, and

meshing with saihi worm is a ratchet toothed wheel 31 which is mounted upon the short shaft 24 so as to be rotatable in the housing 23. Serving to permit the ratchet wheel 31 to be manually rotated to operate the worm 3 for revolving the sliaft 28, whereby the fan 29 may be operated, on the short shaft 24 and exteriorly of the barrel 10 is a crank handle 32. lrVhen the cleaneris in use it is carried and guided over the article being cleaned by the handle 23 in one hand of the person operating it and through the arrangement of the cranlr handle 32 the device may be conveniently operated at the same time by the other hand of the person.

For the purpose of collecting the dust, or refuse which is admitted into the barrel 10 through the nozzle 16, the pipe 15, and the tube 1.4, I provide a receiver, or bag, as 33, which is made of cloth, or other suitable woven material having interstices therethrough. ceiver, or bag 33 is fastened to a split ring 34 which isprcferably made of spring metal so as to-be sprung into the annular groove 12 of the barrel 10. The opposite end of the bag 33 is connected to the free end of a bracket 35 which is formedof two substantially U-shapd 'membcrs of wire, or other metal projcctip inwardly of the barrel 10 from the tube 4, and which aredisposed in cross-wise arrangement When the admixture of air-and dust is admitted into'thc barrel. 10 it is received by the bag 33. The air will pass through the interstices ofthe bag while the dust will be collected upon' the .innersurl'ace thereof, and when it is desired to emptythc bag of accumulated refuse the cap 13 is removed from the tapered end ef the barrel 10. The tube 14,

claim as new and desire to One end of the intersticed re--- the bracket 35, and the ba 33 will thereby be directed outwardly of the barrel 10, and the bag may be emptied of its refuse in any suitable manner. I

In the foregoing description, I have embodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modifications may be made therein without departing from the principle, or sacrificing any of the advantages of this invention, therefore I reserve to myself the right to make such changes as fairly fall within the scope thereof.

Having thus described my invention, I

secure by Letters Patent 1.
